Abstract

The invention relates to a PbSe quantum dot doped sodium aluminum boron germanate glass optical fiber (QDFA). According to the invention, the quantum dot doped fiber (QDF) with the embedded particle size of 4.085.88 nm is prepared by optimizing melting annealing heat treatment conditions. The prepared QDF has strong and stable photoluminescence (PL) emission in the NIR region. The QDFA comprises aQDF, a wavelength division multiplexer, an isolator and a pump laser. It can be seen that a broadband signal in the QDFA is amplified in a wavelength range of 1260-1380 nm, specifically depending onthe size of QD. The switching gain at the central wavelength is 16.4 dB, and when the power of an input signal is 17dBm, the 3-dB bandwidth reaches 80nm. Excitation thresholds and gain saturation arealso observed in experiments. Glass-based QDFA shows a novel method, the current wave band of the fiber amplifier doped with the fiber can be expanded, and industrial application is achieved in the future.

Description

Technical field [0001] The present invention belongs to the field of 5 g of fiber sensing applications, and more particularly to an optical fiber amplifier of PBSE quantum doped sodium aluminum boronite glass. Background technique [0002] Fiber amplifiers are an important optical device in fiber optic communication systems. Due to the limitation of the nature of rare earth ions, the bandwidth and gain of conventional fiber amplifiers (such as PED fiber amplifiers, EDFA) cannot be significantly improved. Expected fiber amplifiers with higher performance. Due to the unique quantum constraint effect and optical properties, quantum dots (QD) have recently caught a lot of attention. [0003] In the near infrared band, it has achieved great success in the preparation including PBSE, PBS, and PBTE systems, high-luminous IV-VI QDs. Among them, the PBSE QD having nothing to simultaneously with the structure has an ideal optical characteristic, including a high quantum yield (up to 300% [...
